秘鲁采购需求：和纸胶带、手账贴纸、硫酸纸便签、日记卡、胸针、金属书签

I'm launching an online shop focused on washi tape and I'm in search of a reliable manufacturer for a dropshipping/print-on-demand setup. My goal is to streamline the process: when a customer orders, I'll pass it to you directly for printing and shipping without holding any inventory on my side. Can you accommodate this model? Specifically, I'd like to know if you can work with single roll orders, your typical lead times, if you can ship without supplier info, and what design file formats you accept. I'm looking for a long-term partnership as my sales volume increases.
